Answer:

Step-by-step explanation:

1) 5xy - xy + 2x - 13x + 10xy - 8x = 5xy - xy + 10xy   +2x - 13x - 8x

Combine like terms

 =  (5 -1 +10)xy + (2-13-8)x

 = 14xy + (-19x)

 = 14xy - 19x

2) -6c - (-6c) - (+6c) = -6c + 6c - 6c

                               = (- 6 + 6 - 6)c

                                = -6c

3) 0x - 22x - 4(2x) = 0x - 22x - 8x = -30x
